RVUE
1  Extracted from Forward Dispersion Relations using sequences of Pade approximants .
2  Extracted from Breit-Wigner parameters.
3  Fit to scattering phase shifts using UChPT amplitudes with explicit resonances.
4  Supersedes BUGG 2006 . Combined analysis of ASTON 1988 , ABLIKIM 2006C, AITALA 2006 , and LINK 2009 using an s-dependent width with couplings to ${{\mathit K}}{{\mathit \pi}}$ and ${{\mathit K}}{{\mathit \eta}^{\,'}}$ , and the Adler zero near thresholds.
5  From a complex pole included in the fit. Using parameters from the model that fits data best.
6  Reanalysis of ASTON 1988 , AITALA 2002 , and ABLIKIM 2006C using for the $\kappa$ an $\mathit s$-dependent width with an Adler zero near threshold.
7  Using Roy-Steiner equations (ROY 1971 ) consistent with unitarity, analyticity and crossing symmetry constraints.
8  From UChPT fitted to MERCER 1971 , BINGHAM 1972 and ESTABROOKS 1978 . Amplitude shown to be consistent with data of ABLIKIM 2006C.
9  Reanalysis of ASTON 1988 data.
10  Reanalysis of data from LINGLIN 1973 , ESTABROOKS 1978 , and ASTON 1988 using the Inverse Amplitude Method.
11  Reanalysis of ASTON 1988 using interfering Breit-Wigner amplitudes. Extracted from Breit-Wigner parameters.
12  Unitarized Quark Model.
